Conformational Changes in Ribosomal Ribonucleic Acid
Both rat liver and Escherichia coli rRNA in 0.1M-sodium chloride were titrated with acid or alkali over the range pH 3-7 at approx. 0°C. rRNA did not bind acid reversibly and hysteresis was observed, i.e. the plot of acid bound to rRNA against pH had the form of a loop showing that the amount of acid bound at a particular pH depended on the direction of the titration. Although the boundary curv...
متن کاملMolecular integrity of plant ribosomal ribonucleic Acid.
Thermal denaturation of plant ribosomal RNA followed by gel fractionation shows that although a large percentage of molecules contain breaks in the polynucleotide chain, 25S and 18S RNAs do exist as unique molecular species. Values for the rate constant of hydrolysis under routine denaturing conditions are of the order of 10(-7) to 10(-8) sec(- 1) and these are shown not to be a result of ribon...
متن کاملRibonucleic acid metabolism in lymphocytes stimulated by phytohemagglutinin. II. Rapidly synthesized ribonucleic acid and te production of ribosomal ribonucleic acid.
Human peripheral lymphocytes are stimulated to change, in vitro, from a resting state to one of progressive enlargement, culminating in mitosis, by treatment with Phaseolus vulgaris phytohemagglutinin. The sedimentation characteristics and fate of rapidly synthesized RNA have been studied in this system after 20 hours of stimulation with phytohemagglutinin, a time when RNA synthesis has been ac...
متن کاملThe genes for cytoplasmic ribosomal ribonucleic Acid in higher plants.
The genes for cytoplasmic ribosomal RNA are partially resolved from the bulk of the DNA by CsCl equilibrium centrifugation. Although in some plants the buoyant density of the ribosomal RNA genes is as expected from the base composition of ribosomal RNA, others show a large discrepancy which cannot be due to the presence of low G-C spacer-DNA. The cross-hybridization observed with 1.3 and 0.7 x ...
متن کاملThe secondary structure of ribosomal ribonucleic acid in solution.
1. The u.v.-absorption spectrum of ribosomal RNA from rabbit reticulocytes was studied as a function of temperature at different pH values. The changes in the spectrum over the range 220-320mmu were interpreted on the basis of the assumption that the effect of denaturation and ionization are additive. The results suggest that in neutral salt solutions the secondary structure of the ribosomal RN...
